Ballot secrecy with malicious bulletin boards

David Bernhard and Ben Smyth

Abstract: We propose a definition of ballot secrecy in the computational model of cryptography. The definition builds upon and strengthens earlier definitions by Bernhard et al. (ASIACRYPT'12, ESORICS'11 & ESORICS'13). The new definition is intended to ensure that ballot secrecy is preserved in the presence of malicious bulletin boards, whereas earlier definitions only consider trusted bulletin boards. It follows that the new definition prevents more attacks in comparison with earlier definitions.
